Answer:
1. D. Evaporation
2. A. A closed lake has no outlet stream.
3. C. The angle of the slope
4. C. Granite
Explanation:
1. The process through which water changes its state from liquid to gaseous is known as evaporation. A source of energy is required for this process to occur, energy that is provided by solar heat in this case. The opposite process in which water changes state from gas to liquid, is known as condensation. Precipitation is the process in which the condensed water reaches the Earth’s surface under the force of gravity. During infiltration, water on the ground surface enters the soil.
2. A closed lake is defined by the lack of any outflow. Thus, any water that does not evaporate, will remain in this type of lake indefinitely.
3. The only criterion not used to describe a mass movement event is the angle of the slope. For such an event, the type of motion is the most important characteristic together with the physical characteristics of the material.
4. Granite is a highly consolidated material and thus it has a very high integrity. The other materials listed have inferior characteristics.
5. Soil erosion is a displacement process that occurs naturally though the action of water and wind. On a steep slope, no soil formation occurs, because, due to gravity, all the eroded material will be transported to another location. Thus, at the slope’s location, no soil formation occurs.
The correct answer is option D, difficulty of redesigning workable ecosystems
Reason -
The area that was redesigned into an ecosystem actually failed to attract the endangered species of clapper rails in California because of the following two reasons –
a) Failed attempt of restoration of Cord grass ( a tree which is a dominant tree in the nesting habitat of clapper rail) . Even if few such trees were there they could not grow to their full height and thus were incapable of providing adequate nesting cover
b) Due to the lack of predatory insect, some herbivore insect in the ecosystem attacked the green grasses thereby making the nesting inadequate.
Answer;
-Because of Homeostatic imbalance as we age our body organs become less efficient, and our internal conditions become less and less stable. This event has a risk for illness and produce changes we associate with aging.
Explanation;
-Homeostasis is the body's ability to maintain a relatively stable internal environment even though the outside world is constantly changing. It involves both positive feedback Loops and the negative Feedback loops.
-Aging is a general example of disease as a result of homeostatic imbalance. As an organism ages, weakening of feedback loops gradually results in an unstable internal environment. This lack of homeostasis increases the risk for illness and is responsible for the physical changes associated with aging.
